Midterm results and quality of life after minimally invasive vs. conventional aortic valve replacement.

摘要: BACKGROUND This study compares early and mid-term results as well the quality of life (QOL) between minimally invasive conventional aortic valve replacement (AVR). METHODS Between 7/97 4/01, 70 patients (mean age 64.3 +/- 1.3 years) underwent AVR (group M) through an L-shaped ministernotomy. The were compared to those C) during same period. Patients equally matched according age, sex, ejection fraction, valvular lesion, prosthesis. In groups M C, follow-up was 98.5 % 95.4 complete averaged 34.0 10.3 33.1 12.9 months, respectively. RESULTS There no hospital deaths in group but two C (p = n. s.). Conversion full sternotomy necessary patients. Cross-clamping time (71 15 min vs. 58 18 min), cardiopulmonary bypass (105 22 84 24 surgery (228 45 184 48 min) significantly longer M. No statistically significant differences for postoperative ventilation time, transfusion rate, ICU stay or length recorded. At end follow-up, 96.9 free thromboembolism s.), 100.0 endocarditis reoperation s.) C. Survival 97.0 91.9 ns). any 8 QOL categories, patient satisfaction with operative result judgment cosmetic aspect noted among groups. CONCLUSIONS has failed show advantage midterm follow-up.
